There's definitely just another whining sound coming from him when Tidus laughs. Inigo can't help but be even more sensitive to that than usually when he's feeling so out of his element.

"I've got plenty to worry about since it's so strange!" But he's still kicking! Even though he doesn't exactly look like he's having fun either... "S-So I can't just.. relax! Sheesh.."

He sucks in a breath before slowly opening his eyes - first just a quick peek, but then he keeps them open.

"I usually don't get scared so easily, you know." Which is true. He can fight the monsters during missions just fine, he hasn't felt scared even a single moment during any of that. It takes other situations entirely to scare him. "So don't think I'm a coward."
